A display device includes a display region in which a plurality of pixels are arranged two-dimensionally. Each of the plurality of pixels includes a light-emitting layer and an optical member that refracts light from the light-emitting layer. In an orthographic projection of a first optical member included in a first pixel with respect to the light-emitting layer, a position of an apex of the first optical member and a position of a center of the first optical member are separated by a first distance.

Display device and display system

After accumulating electric charges in pixels in first, second, and third rows, signals are output from the pixels in the first and second rows in a first frame, and thereafter, after accumulating electric charges in the pixels in the first row without accumulating electric charges in the pixels in the second and third rows, signals are output from the pixels in the first and third rows in a second frame following the first frame. Furthermore, the photoelectric conversion units of the pixels in the second and third rows are reset by the resetting units included in the pixels in the second and third rows in the first frame.
